To all eri/tom t may concerne:

Be it known that I, ALFRED F. BISHOP, a citizen of the United States, residing at Aro dubon, in the county of Camden and State of New Jersey, have invented certain'new and useful Improvements -in a Shrubbery Clipper, of which the following is a specification.

My invention relates to improvements in clippers for trimming shrubbery :and the like. The object of my invention is to construct a clipper which may be easily operated and which `will be light inweight, adapting the same for use on large hedges whereby the trimming of the hedge may be done quickly and uniformly; a furtherjobject of my invention is toformthe main base bar having the fixed cutting blades; formed thereon of pressed steel; The base bar Vand the blades are of coneaved formationy with upstanding edges, thus forming a rigid construction which is light in weight, the upstanding edges extending aroundtheffixed blades and forming the cutting' edges; 'further object of my invention is to provide separate loosely pivoted blades upon the base bai; which are adapted'to tiltslightly during the cutting action and thus iinpinge tightly upon the upstanding cutting edges of the fixed blades, and thus forming an effective cutting action; a still further object of my invention is to provide fastening devices upon either end of the base bar kin which may be adjust-ably secured handles for supporting the clipperl either by one or two persons, and also provide operating handles by which thepivoted blades may be operated from either end of the base bar; said operating handles being adjustable radially7 and provided with rotatable hand grips for the convenient operation of the device.

Referring to the accompanying drawing, Fig. 1 is a plan view of my improved clipper; Fig. 2 is a vertical section online 2-2, Fig. 1; Fig. 3 is a vertical section on line 343, Fig. 1; Fig. l is a vertical section on line 4-4, Fig. 3; and Fig. 5 is a vertical section on line 5 5, Fig. 3.

In the drawing, in which like reference characters refer to like parts, 1 represents the base bar having the fixed blades 2 formed thereon. Upon the base bar 1 are pivotally mounted the blades 3. which cooperatexwith the blades 2 and form the cutting action. Bolts 4 are provided for pivotboss 22. -ed with aconica'l recess 23, which is occually attaching the blades 8 to the base bar 1. rlhe pivoted blades 3 are all pivotally attached, by bolts 5, toy a ronneeting barwG, which latterl is pivotaliy connected, by bolts 7. withV the operating handles 8 and 9,

which in tarn are pivotally attached to the base bar 1.1 adjacent to either end of the latter, bythe bolts 10.

y, The base bar 1 is provided with fastening devices 12 and 13, secured at either end thereof, consisting of bracketsjhavingsockw ets formed `therein adapted vto receive the Shanks 15 of the supporting handles 16 or 1T.M Said brackets are provided with set screwsv 18 for detachably securing the Shanks 15in the brackets, making either of the'handles 16er 17' readily removable. Said yshanksl are 'bent slightly so that the handles maybe set at various anglesin relation to the base bar 1;

.The operatinglarnisor handles Sand 9 are each made in two sections 19y and 20, which are secured together by a bolt21, by which the section 20 may be placed invarious yradial positions in relation to the Isupporting handlel 16 or 17. The section 19 of the handle 8 or 9 is provided with a conical The yopposite section 20 is providpied by the boss 22 and saidisections 19 Aand 2O are adapted to` be tightly clamped together by the bolt 21, after the handle sect-ion 2O is set at the desired angle in relation to the section 19. Y

The handle section 20 is provided with a knob 25 forming a suitable hand grip,

`which knob is rotatablyv mountedv upon a pin 26 secured vin the handle section 20.

The base bar 1, having the fixed blades 2 formed thereon, is pressed from sheet metal. Formed upon the base bar 1 are rip-standing edges 28 and 30. The edge 28 extends throughout the length of the base bar 1 and forms a stiifening member for giving rigidity to the bar 1 and permitting the same to be of sufficient length for trimming wide hedges and also permit-ting the base bar to be of light construction. The upstanding edge 30 formed on the base bar 1 extends around the blades 2 and thus forms the cutting edges on said blades 2. Each blade 2 is of hollow or conca-ved formation between the cutting edges 30, whereby the material when cut will more readily free itself from the blades and thus prevent the blades from clogging and binding.

llO

The *psa-ea mais s sa aa intensa With a rounded lunder surface 32 located at the cross-section of the blade `ivi/Thiel; rests upon the longitudinal upstanding edge 28' of the base bar l, as shown in 4. Said edge 28 forms a bearing surface upon which this rounded surface 32`ofthe pivoted blade 3 may rock during the Ycutting action. The pivot bjolt i by which the blade 3 is pivoted to the base bar '1 Vis sufficiently loose, as is also the 'bolt 5 which connects thel blade 3 With the 'connecting bar 6, 'to permit 'the blade 3 to Ahave a slight 'rocking "movement y The pushing and pulling'actio-n of vthe 'conf necting bar 6 Will tend torock the "pivoted blades 3, causing the double cutting edges vbleach pivoted blade 3 to tightly limpinge upon the cutting edge 30, of first 'one fixed blade QLthus giving "a very 'effective cutting action to the blades.
